Email marketing has been a cornerstone of digital marketing for decades, helping brands connect with customers, nurture leads, and generate impressive returns. But in recent years, another channel has rapidly gained traction — SMS marketing.
For businesses and marketers, the challenge isn’t deciding which channel is “better,” but rather how to integrate SMS into your email marketing strategy to get the best of both worlds. In this guide, we’ll break down the differences, best practices, and winning strategies for combining these two powerhouse channels.
